We can understand someone dying for a person worth dying for, and we can understand how someone good and noble could inspire us to selfless sacrifice. But God put his love on the line for us by offering his Son in sacrificial death while we were of no use whatever to him. Now that we are set right with God by means of this sacrificial death, the consummate blood sacrifice, there is no longer a question of being at odds with God in any way. If, when we were at our worst, we were put on friendly terms with God by the sacrificial death of his Son, now that we’re at our best, just think of how our lives will expand and deepen by means of his resurrection life! Now that we have actually received this amazing friendship with God, we are no longer content to simply say it in plodding prose. We sing and shout our praises to God through Jesus, the Messiah! Romans 5:7–11 (The Message)
There's an old Calvin and Hobbes comic strip in which Calvin is griping to his dad, so his dad explains that life isn't fair. "I know," Calvin replies, "but why isn't it ever unfair in my favor?"
Good Friday is the day life was unfair in our favor, the day we got exactly what we didn't deserve. Just think of how our lives will expand and deepen by means of his resurrection life. Just think.
